E5500 Phase Noise Measurement System Version A.02.00
This example contains information about measuring the residual
noise of two port devices
This example demostrates a residual phase noise measurement for
an RF Amplifier. Refer to
Fundamentals" for more information about residual phase noise
measurements.
CAUTION:
To prevent damage to the Agilent 70420A test set's hardware
components, the input signal must not be applied to the signal input connector
until the input attenuator has been correctly set for the desired configuration, as
show in
Table
9-2. Apply the input signal when the connection diagram appears.
Table 9-1
shows equipment required for this example in addition to
the phase noise test system and your unit-under-test (UUT).
NOTE: To ensure accurate measurements, you should allow the UUT
and measurement equipment to warm up at least one hour before
making the noise measurement.
